References C. Kingsley Adams. "Portraiture Problems and Geneology." The Geneaologist's Magazine 14, no. 11 (September 1964), pp. 387–88, explains how the sitter for three pastels by Rosalba, including the present work, came to be identified as Horace Walpole and that he is instead the 2nd Viscount Boyne. C. Kingsley Adams W. S. Lewis. "The Portraits of Horace Walpole." Walpole Society 42 (1968–70), pp. 27–28, no. C.5, pl. 28c, identifies the sitter as Gustavus Hamilton, 2nd Viscount Boyne. Francis Russell. "The British Portraits of Anton Raphael Mengs." National Trust Studies 1979 (1978), pp. 14, 16, notes that a pastel portrait of William Burton, later Conyngham, by Mengs was framed in the eighteenth century as pendant to a version of Rosalba's portrait of Lord Boyne [this picture]; suggests that the Mengs pastel [now J. Paul Getty Museum, Malibu] was commissioned as a pair to Rosalba's, probably for the 1st Earl of Leitrim. Bernardina Sani. Rosalba Carriera . Turin, 1988, p. 311, no. 268, fig. 235, calls it "una bellissima replica" of the London pastel; gives incorrect dimensions. Francis Russell. "Book Reviews: Rosalba Carriera by Bernardina Sani, 1988."

Exh. cat.London, 1993, p. 58, supports Russell's view that a pastel by Mengs of William Burton Conyngham (private collection) was made to match a pastel of Lord Boyne by Rosalba Carriera [this work]; comments on their matching frames and on the rarity of pastel for grand tour portraits.

Munich, 1999–2003, vol. 1, p. 274, states that the frames for this portrait and Mengs's portrait of Conyngham at Killadoon are nineteenth-century (rather than eighteenth-century), and thus cannot lend support to the identification of the two pastels as pendants.

(color, framed and unframed), states that it was painted in 1730 or 1731, when Lord Boyne stayed several times in Venice during his Grand Tour.
